Letters'latent N 10(1),488, dated March 8, 1870.

'The Schedule referred to in these Letters Patent and making part of thesame.

To all whom Iit moy concern:

Be it known that I, PARLEY J .Avans of Lydon, in the `county of Lewis,and Stat-e of NewV lYork, have invented a new and improvedTire-Upsett-ing Ma'- chille; and l. do hereby dec-lare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referenceheilig had to the accompanying drawings forming part of tlli'sspecification.

This invention relates to improvements ill macllines for upsetting tireand metal bars, and has for its object to provide a simple, elicientapparatus especially y adapted for readily applying and removing thetires.

j lhe invention comprises'a main bed of castmetal, with a verticalxedlpillar, a'slitlingbed withanotliel' pillar, a pair of clamping dogs,a pair of supporting links for the pivots of the dogs, and an eccentric'operating lever, all arranged as hereinafter more fully specitied. l

` Figure l represents a side elevation of my improved machine, and fFigure 2 represents a plan viewv of the same. `A represents thepermanent bed; and

Il', the sliding bed. p C represents the pillar of the permanent bed;and 1), the pillar ofthe sliding bed.

the latter is provided with suitable side guides E fixed to thepermanent bed, and at the end where the pillar C is placed, anelevation, B', is raised, similar ill size and cross-section to thesliding bed, but hollowed for a reduced part ofthe latter to slideunder.

Each pillar is provided with a pawl or jaw, F, suspended from pivotbolts at the top of the pillars, so` that their lower ends reach lnearlyto the upper sur faces ofthe bed B, and the elevation B', respectively.

Under these jaws the-parts B B are stacked and serrated, or steel wedgesmay be placednnder them with serrated faces.

The jaws F have curved levers L rising above them, and bent inward, so.as to have a ten ency to throw the points outward. These hand 4es servealso for raising the jaws when the bar is to be inserted.

K represents links connected to the pivot bolts, and arranged to engageat the lower ends with-therlugs L to support the pivot bolts understrain. f

M represents the eccentric lever for forcing up the slide B. V

For operatilm this slide is drawn back, the links disengaged, the pillsraised, and the heated tire or bu' placed under the jaws; they arethenaliowed to fall down to engage the tire. The lillks are tllenhookedunder the lugs, and the machine is'really for operation by working thelevel' to force the part B toward the part B,`which may be done severaltimes at 4one heat of the tire, the eccentric being arranged -to drawthe part B back, which the jaws permit heilig shaped and arranged tohold the bar firmly Iwhen the parl B is thrown inward, but to be drawnalong the har readily when moved the other way.

Having thns described my invention,

I claim as new and desire to secure by Letters Patent-- p Thecombination of the permanent hed A B', movable bed B, jaws F, benthandles l, pillars C D', bolt G, links K, projections L, al'ldoperatingeccentric lever M, all` substantially as specified.
